Title: Electronic metal coin analyser
IPC: G01N27/02
Filed: 1970-03-25
Abstract: 1,254,269. Registering and testing coins. F.A.T.M.E. FABRICA APPARECCHIATURE TELEFONICHE E MATERIALE ELETTRICO " BREVETTI ERICSSON." 25 March, 1970 [31 March, 1969], No. 14489/70. Heading G4V.  All varieties of coin which can be inserted.- through a slot fall-down shoot 12, thereby passing inductance coil 20. Coil 20 forms part of oscillator circuit 34 and the increase in inductance caused by ferromagnetic coins and the decrease in inductance caused by other coins alters the frequency of the oscillator. The change in inductance depends upon the size, shape and composition of the coin so that each type of coin produces a characteristic frequency in oscillator 34. Filters F i  may be tuned to each of these frequencies but preferably the signal is mixed with a second signal of frequency close to that of the undisturbed oscillator 34, and the filter circuits tuned to the difference in frequencies, so as to improve discrimination.  The signal produced by a valid coin will be passed by the appropriate filter circuit, amplified at 36, rectified at 38 and passed to relay 40. Relay 40 will be actuated only by a pulse of minimum duration of the order of the time in which the whole coin is within the coil. The discrimination of the filter circuits is thus enhanced, because a brief pulse of correct frequency which might be produced by a coin of marginally incorrect properties as it approaches and/or leaves the coil is thus rejected. The passage of each valid coin therefore results in the emission of a pulse from its corresponding relay 40. The pulse is transmitted along line 42 to a counting circuit and to OR gate 44 which transmits a pulse via amplifier 46 to relay 28 so as to move deflector 26 to cover the return coin shoot 32 and thus allow valid coins to pass to the cash box via shoot 30.

Title: Temperature control for mechanical or absorption type refrigerators
IPC: G01K1/22
Filed: 1936-05-25
Abstract: 461,729. Thermostats. TRIGGS, W. W. (Allyne International, Ltd.) May 25, 1936, No. 14757. [Class 135] [Also in Groups XIII and XXXVII] A temperature-control device suitable for refrigerators comprises a bulb 6 containing an expansible fluid connected to a bellows 2, the move. ments of which are adapted to actuate a switch 11 or valve 11<1>. A vessel 15 and Bourdon tube 19 are filled with a suitable organic salt or the like which is liquefiable by heat. In operation, the bulb 6 is in the food compartment of a refrigerator and if the temperature rises the bellows 2 expands to actuate the switch 11 to start a compressor unit or the valve 11<1> to turn on the fuel valve to generate a refrigerating cycle. This action takes place if the room is also warm, when the filling of the tube 19 is liquid, so that it offers no resistance to the movement of bellows 2. If the room is cold, it is unnecessary for the refrigerating cycle to operate as quickly, so that the resistance of the tube 19 when its contents are solid delays the expansion of bellows 2 until a further rise takes place in the food compartment,

Title: Method of detecting the end-of-charge condition of an electric storage battery under charge and device for the carrying out of this method
IPC: H02J7/04
Filed: 1970-03-26
Abstract: 1,267,339. Charging batteries. LECLANCHE S.A. 26 March, 1970 [28 March, 1969], No. 14761/70. Heading H2H.  A method of determining when a battery is fully charged during a charging process which includes periodic interruption of the charging current involves deriving a signal which is related to the voltage decrease of the battery when disconnected, comparing this signal with a signal representative of the battery voltage at the instant of the charging current interruption, integrating the difference between the signals and applying the integrated result to a device having a threshold point related to the full charge of the battery so as to operate the threshold device when the battery is fully charged to terminate the charging process. A battery 1 is charged from a D.C. source 2 under the control of a unit 4 which periodically energizes and de-energizes a relay 3 thus closing and opening a contact 3a whereby the battery charging current is periodically interrupted. A further contact 3b simultaneously energizes and de-energizes a relay 5 so that when the battery 1 is being charged a capacitor 7 in an integrating unit 8 is short-circuited and a capacitor 6 is connected across the battery 1 so as to be charged to a voltage equal to the battery voltage. When the relay 5 is de-energized during the periods when the battery charging current is interrupted a differential amplifier 10 in the integrating unit 8 receives two input voltages, one from the capacitor 6 and one from the battery 1 by way of a resistor 9, the unit 8 operating to integrate the difference between these two voltages, that from the battery 1 decreasing during the period of current interruption. The integrated output from the unit 8 is applied to a threshold device 11 together with an input from the battery 1, the output from the unit 11 being operative, when the inputs indicate a fully charged battery, to operate a relay 12 so to terminate the charging process of the battery 1.

Filed: 1970-03-31
Abstract: 1,268,978. Making electrical contacts; work guides. BUNKER-RAMO CORP. 31 March, 1970 [14 April, 1969], No. 15061/70. Headings B3A and B3W. [Also in Divisions C7 and H2] An electrical contact is made by forming spaced apart locating pilots in a metal tape 24, selectively coating the tape 24 which resist material so as to form regularly recurring non- coated areas 40, plating a non-corrosive metal on to the non-coated areas 40 of the tape 24, removing the resist material and punching and forming the tape to form individual contacts, each having a plated wear area adapted to engage a similar wear area on another contact. A cadmium bronze tape 24 is passed through a punching press (22), (Figs. 2 and 4, not shown), where pilot holes 25 are formed by a punch (26b). The tape 24 is currently positioned by a side guide (26c) and a locating pin (26a) engaging a previously formed hole. Alternatively, the tape 24 may be provided with printed or embossed areas adapted to be sensed in subsequent processing steps. After cleaning the tape at (30), it is selectively coated with printing ink by rollers (34), (Fig. 5, not shown), so as to form non-coated areas 40, the ink being dried at (36). The holes 25 in the tape 24 are engaged by projections (38) on the rollers (34) so as to precisely locate the bare areas 40. The tape is next passed beneath cleaning nozzles 41 and into a plating tank 47 containing an anode 48 and supplied with a potassium gold cynanide electrolyte from a reservoir 52 whereby the bare areas 40 are plated with gold having a thickness of 30 micro inches. If a relay 53 detects the absence of plating current, the electrolyte is drained into a container 53A to prevent the cadmium in the tape dissolving in the gold solution. The printing ink is subsequently removed by spray nozzles 44, downstream of which the plating power supply is connected to the cleaned tape 24. After plating, the area of each contact member is precisely located in a punch press 56 and the contacts formed and separated from the tape by dies 57. The contact is formed with a protuberance (20), (Fig. 1, not shown). The contacts are finally electrolessly plated with gold to a thickness of 2-5 micro inches.
